    The Impact of Distributing School Uniforms on Children’s Education in Kenya
    (World Bank, Washington, DC, 2008-03-01) Evans, David ; Kremer, Michael ; Ngatia, Muthoni
    The authors evaluate the impact of an educational intervention, in which a Kenyan non-governmental organization distributes school uniforms to children in poor communities. The Nongovernmental organization (NGO) used a lottery to determine who would receive uniforms. Although compliance with the lottery was not perfect, we use winning the lottery as an instrumental variable to identify the impact of receiving a uniform. The authors find that giving a school uniform significantly reduces school absenteeism by 38 percent. Effects are much larger for poorer students who did not previously own a uniform: a 64 percent reduction in school absenteeism. Preliminary data suggest positive impacts of uniform distribution on test scores in core subjects.

    An Analysis of Clinical Knowledge, Absenteeism, and Availability of Resources for Maternal and Child Health: A Cross-Sectional Quality of Care Study in 10 African Countries
    (World Bank, Washington, DC, 2020-10) Di Giorgio, Laura ; Evans, David K. ; Lindelow, Magnus ; Nguyen, Son Nam ; Svensson, Jakob ; Wane, Waly ; Tarneberg, Anna Welander
    This paper assesses the quality of health care across African countries based on health providers' clinical knowledge, their clinic attendance, and drug availability, with a focus on seven conditions accounting for a large share of child and maternal mortality: malaria, tuberculosis, diarrhea, pneumonia, diabetes, neonatal asphyxia, and postpartum hemorrhage. With nationally representative, cross-sectional data from 10 countries in Sub-Saharan Africa, collected using clinical vignettes, unannounced visits, and visual inspections of facilities, this study assesses whether health providers are available and have sufficient knowledge and means to diagnose and treat patients suffering from common conditions amenable to primary health care. The study draws on data from 8,061 primary and secondary care facilities in Kenya, Madagascar, Mozambique, Nigeria, Niger, Senegal, Sierra Leone, Tanzania, Togo, and Uganda, and 22,746 health workers. These data were gathered under the Service Delivery Indicators program. Across all conditions and countries, health care providers were able to correctly diagnose 64 percent of the clinical vignette cases, and in 45 percent of the cases, the treatment plan was aligned with the correct diagnosis. For diarrhea and pneumonia, two common causes of under-five deaths, 27 percent of the providers correctly diagnosed and prescribed the appropriate treatment for both conditions. On average, 70 percent of health workers were present in the facilities to provide care during facility hours when those workers were scheduled to be on duty. Taken together, the estimated likelihood that a facility has at least one staff present with competency and the key inputs required to provide child, neonatal, and maternity care that meets minimum quality standards is 14 percent. Poor clinical knowledge is a greater constraint in care readiness than drug availability or health workers' absenteeism in the 10 countries. However, the paper documents substantial heterogeneity across countries.

    School Costs, Short-Run Participation, and Long-Run Outcomes: Evidence from Kenya
    (World Bank, Washington, DC, 2018-04) Evans, David K. ; Ngatia, Mũthoni
    Access to school has risen dramatically in recent decades, with large gains from reducing costs. Few studies report long-term impacts, however. This paper reports the impact of an educational intervention that reduced out-of-pocket schooling costs for children in poor communities in Kenya by providing school uniforms. The program used a lottery to determine who would receive a school uniform. Receiving a uniform reduced school absenteeism by 37 percent for the average student (7 percentage points) and by 55 percent for children who initially had no uniform (15 percentage points). Eight years after the program began, there is no evidence of sustained impact of the program on highest grade completed or primary school completion rates. A bounding exercise suggests no substantive positive, long-term impacts. These results contribute to a small literature that demonstrates the risk of fade-out of initial impacts of education investments.
